Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639474, here are decompositions:

13 + 8639461 = 8639474
31 + 8639443 = 8639474
61 + 8639413 = 8639474
73 + 8639401 = 8639474
127 + 8639347 = 8639474
211 + 8639263 = 8639474
223 + 8639251 = 8639474
313 + 8639161 = 8639474

Showing the first eight; more decompositions exist.
